27Note: Dispose of the used oil at a certified recyclingcenter.1 m–3216Figure 241. Oil drain valve7. Remove the oil fill cap and slowly pour approximately80% of the specified amount of oil in through thevalve cover.8. Check the oil level; refer to Checking the Oil Level,page 14.9. Slowly add additional oil to bring the level to the F(full) mark on the dipstick.10. Replace the fill cap.Changing the Oil FilterReplace the oil filter every 200 hours or every other oilchange.Note: Change the oil filter more frequently whenoperating conditions are extremely hot, dusty, or sandy.1. Drain the oil from the engine; refer to Changing theOil, page 26.2. Remove the old filter and wipe the filter adapter(Fig. 25) gasket surface.3. Pour new oil of the proper type in through the centerhole of the filter. Stop pouring when the oil reaches thebottom of the threads.4. Allow a minute or two for the oil to be absorbed byfilter material, then pour off the excess oil.5. Apply a thin coat of new oil to the rubber gasket onthe replacement filter (Fig. 25).m–12561 23Figure 251. Oil filter2. Gasket3. Adapter6. Install the replacement oil filter to the filter adapter.Turn the oil filter clockwise until the rubber gasketcontacts the filter adapter, then tighten the filter anadditional 1/2 turn (Fig. 25).7. Fill the crankcase with the proper type of new oil;refer to Changing the Oil, page 26.Servicing the BatteryCheck the electrolyte level in the battery every 100 hours.Always keep the battery clean and fully charged. Use apaper towel to clean the battery case. If the batteryterminals are corroded, clean them with a solution of fourparts water and one part baking soda. Apply a lightcoating of grease to the battery terminals to reducecorrosion.Checking the Electrolyte Level1. Raise the loader arms and install the cylinder locks;refer to Using the Cylinder Locks, page 20.2. Stop the engine and remove the key.3. Remove the hood, refer to Removing the Hood,page 25.4. Look at the side of the battery. The electrolyte must beup to the Upper line (Fig. 4). Do not allow theelectrolyte to fall below the Lower line (Fig. 4).5. If the electrolyte is low, add the required amount ofdistilled water; refer to Adding Water to the Battery,page 28.
